Electric twin motors for a Central rc marine 51" Victory cat

[wedgewalker]

Can anyone suggest what size motors to go with for a twin set-up. I am currently running a TP 5670 720 kv 5y on 12s. I have the flier model 400a 90v red waterproof esc. I would like to go with two motors and use one esc so I need to keep my amps right at 400 for both motors. This esc is supposed to have a 500a max rating, Is there any way to accomplish this for that hull? I would like to still use 12s, so 1 6s pack per motor.
Thanks,

Glen

You cannot use 1 esc for 2 motors. For 6s use TP 4070 1520KV ABC 2217 props and swordfish 200a escs.

Mark,This esc has six motor wires and 4 power wires, if it can't be used that way is that only because of the capacity?

[MarkF]

Those are rare to see. My motor selection still stands though.That's what I run in my 6s rigger that does high 80s.

Hey Mark! What size hull are you pushing with that set up?

[MarkF]

38" rigger. Your 51" cat will do very well with my setup. Twin motor setup that is.

Just a remark. 6s. is not the best choise. Your lipos will probably have a hard time. So 60C or preferably more would be a good idea....

I have giant power kitty sticks, they are 70c to 140c 6s 6000mah x4, that's two 3s per pack.

The setup I posted is very easy on the equipment. Nothing gets past warm in my boat. A twin will be even easier.

Should motor timing monitor be on or off in esc?

Assuming you are not trying to run a class legal set-up, you can run 12S1P and feed both ESC's with the single battery using the same motors. Just prop accordingly.

Hey Tyler, Thanks! If you saw in my previous post I have a Flier ESC That has six motor wires and 4 battery wires. Can that be for two motors or is it just for high amp setup. I also was wondering if the timing monitor should be on or off in the ESC?

[RaceMechaniX]

Those double ESC's are just two singles placed back to back. They should be connected to two motors individually. You should not try to operate the double ESC connected to a single motor.
you can run both off a single battery if the amp draw on the battery is reasonable.

Ok, I am running a TP 5670 720kv 5Y with that esc. So I should only run off one half of it for 12s or should I get a different esc. My plan is to run two TP 4070s w/6s on each motor and stick with that same setup.
